Brooks Glycerin GTS 21 Running Shoes

Lace up and head out in supreme comfort. For the Glycerin GTS 21, Brooks has added 2mm more super soft DNA LOFT v3 cushioning for extra plushness, while their innovative GuideRails support system keeps you comfortably in stride. Plus an updated, streamlined upper adds breathability.

Engineered Warp Knit Upper

With a new, engineered warp knit upper, the Brooks Glycerin GTS 21 offers exceptional breathability alongside a flexible and accommodating fit that stays soft against your foot. The engineered upper encourages cool air to permeate the fabric, removing uncomfortable heat build-up to maintain a cool, regulated temperature for a healthy environment where feet can thrive. The knit feels soft for supreme and smooth comfort surrounding the foot. A padded collar and tongue provide exceptional comfort whilst reducing chafing and rubbing. Finished with a traditional lace system, the Glycerin GTS 21 offers a secure, locked-in feel that reduces in-shoe slippage.

DNA LOFT v3 Midsole

Featuring the same DNA Loft v3 technology as the Glycerin 20, the Brooks Glycerin GTS 21 is soft and comfortable. This new and updated version has 2mm more of this super-soft, nitrogen-infused cushioning technology to maximise softness. The DNA LOFT v3 cushioning carries the footwell and even moulds itself to the shape of the underfoot, allowing the platform to fully support the curvature of your foot. Infused with nitrogen to be as soft, light and durable as possible, Brooks' DNA LOFT v3 has been designed to be super soft. Having this cushioning and support helps lessen the impact placed upon your joints and absorbs shock, minimising the potential risk of injury or discomfort. Thanks to the added 2mm cushioning, the Glycerin GTS 21 further enhances this when compared to the previous version. The plush midfoot transition zone is designed to propel your movements from heel to toe, especially for a neutral runner to maintain the most efficient gait possible for a smoother ride. Lastly, the Brooks Glycerin GTS 21 features industry-leading support for supreme comfort. Brooks' innovative GuideRails technology supports your foot in its natural motion path while keeping excess movement to a minimum.

RoadTack Rubber Outsole

Designed with a broad platform, the Glycerin GTS 21 stabilises your foot and promotes smooth heel-to-toe transitions throughout wear. A new RoadTack rubber features on the outsole to provide exceptional durability that delivers a sustainable performance time and time again. This RoadTack rubber includes recycled silica for a lightweight and durable finish. In addition, the outsole possesses high grip and traction properties to ensure a firm, assured foothold so you can run with both comfort and confidence. Lastly, the shoe can flex as one with the foot instead of restricting it without compromising grip and durability for a more comfortable and confident ride.
